PAPER WAXING AND CUTTING MACHINE.

SPECIFICATION forming part'of Letters Patent No. 404,151, dated May 28, 1889.

Application filed November 3, 1888. Serial No. 289,899. (No model.)

.To all whom it may concern:

Be it known that I, J OSIAH BURNHAM AN DERSON, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Paper \Vaxing and Cutting Machines, of which the following is a specification.

My invention consists in improvements in machines for waxing or gumming and cutting paper.

It is the object of my invention to provide a machine capable of waxing or gumming paper in a more expeditious manner than is now done and to accomplish this without waste of material, and in the same machine and at the same operation to cut the paper into sheets suitable for packing for commercial use. i

I will first describe my invention in connection with the accompanying drawings, forming a part of this specification, and subsequently point out the improvements in the appended claims.

Of the drawings, Figure 1 represents a top plan view, partially in section, of the machine. Fig. 2 is a side elevation of the same.

The same letters and figures designate the same parts in both views.

In the drawings, A designates the frame, of any character and material suitable for supporting the operative parts of the machine.

The paper to be treated may be a continuous web wound into a roll, a, from which it may be'drawn, or it may be taken directly from the paper-making machine and treated by my improved contrivance. From the roll a the paper passes under a tension-roller, b, and from thence between two hollow heated cylinders, c d, the former cylinder, 0, spreading an even coating of wax or gum, as the case may be, on the upper side of the paper, and the two cylinders together acting to eifeet a quite thorough infusion of the wax into the paper.

6 designates a tank adapted to contain wax or gum,which tank may be supported from the ceiling, as shown, or in any other suitable manner, over'a hollow heated cylinder, f, rolling in contact with cylinder 0. The bottom of tank e is concaved, so as to encompass the upper portion of cylinder f, and said bottom is provided with numerous fine holes or perforations, and a slide, g, constructed in like manner, is arranged and adapted to be moved or adjusted on the bot-tom of the tank so as to entirely close the holes or perforations therein or open them partially or fully, as may be needed, to regulate the supply of wax or gum conveyed to cylinderf, and by it distributed upon cylinder 0. By thus constructing the tank 6 and slide h with a series of holes or perforations no detriment is caused by the wax partially stopping up some of these holes or apertures, and hence the wax is equally distributed over the cylinders and by them transferred to the paper.

72, designates a pipe in tank 6, adapted to receive steam or hot air or hot water for the purpose of keeping the wax or gum in a perfectly liquid state. A number of these pipes It may be arranged in tank 6.

From cylinders 0 (Z the paper passes under a tensioi'i-roller, 1', thence between heated rollers or cylinders j k, and thence under and over plain or figured rollers Z we to the table 21, where it passes under a chemically-cooled tube, 0, which cools the surface of the paper along the line where the rotating circular knife 1) operates to cut the sheet or web 1011- gitudinally. Said knife 17 is driven by a belt, 2, passing over pulley 3, operated by any suitable means, the knife and pulley being supported in a bracket or hanger, =l-, secured to the ceiling.

The cooling-tube O projects over the table to a point in front of and in a line with the rotating knife, considered with respect to the direction of traverse of the paper over the table. The wax on the paper is cooled to a certain degree by the atmosphere, and is thoroughly chilled along the line when it passes under tube 0 before being cut by the knife 19.

From the knife 1) the paper passes between rollers q 0', provided with blades 8, having serrated or similarly-formed edges by which the web of paper is cut transversely into sheets. From this point the sheets pass under guiderollers t t, or between pairs of such rollers, which guide and conduct it between finishingrollcrs a r, whence it passes over a cylinder, 10, into a box. or receptacle,

A tank,g similar in construction to tank 6, is arranged over rollers u 1;, which tank y is supplied with powdered soapstone or the like, which is sprinkledon roller u and by the latter conveyed to the paper to prevent the sheets from sticking together after they pass into box on.

By the means described paper can be thoroughly waxed or gummed in an expeditious manner and be cut into sheets so as to be commercially packed without need of a second handling or manipulation, as is the case in machines as now commonly constructed.

It is obvious that parts of my improved ma chine may be varied in form and arrangement without departing from the nature or spirit of the invention.

What I claim is I 1. In a paper Waxing and cutting machine, the combination of the vertical series of cylinders c d f and a wax-receiving tank arranged above said cylinders and encompassing the upper portion of the upper cylinder. f, and provided with a perforated bottom, and a slide provided with perforations. designed to register or coincide with the perforations of said bottom to regulate the supply of wax, substantially as set forth.

2. In a paper waxing and cutting machine, the combination, with the waxing-rollers and the table a, of means to draw the paper thereover, the cooling-tube O, and the rotating knife arranged adjacent to said cooling-tube, such tube projecting over the table to a point in front of and in line with the rotating knife, considered with respect to the direction of the traverse of the paper, as set forth.

In a paper waxing and cutting machine,

the combination, with the waxing-rollers and,

traverse of the paper, substantially as set forth.

4. The herein described improved paper waxing and cutting machine, comprising the series of cylinders 0 cl f, awax-receiving tank located above said cylinders and provided with a perforated bottom, the perforated slide within said tank, the series of guide and tension rollers, the table 11, the rotating cuttingknife, the cooling-tube projecting over i the table to a point in front of and in line with the rotating knife, considered with respect to the traverse of the paper through the machine, the cutting-rollers q r, the finishing-rollers, the dust-receiving tank located above said latter rollers, and the paper-receiving box, all constructed and arranged substantially as set forth.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses,this 29th day of October, A. D. 1887.

It is hereby'oertifiedthat Letters Patent No. 4(l4,151, granted MayQS, 1889, upon the application of Josiah Burnharn Anderson, of Boston, Massachusetts, for an i1nprovement in Paper Waxing and Cutting Machines, Were erroneously issued to said Anderson as owner 0f the invention; that said Letters Patent should have been issued to George H. Heath, of same place, assignee of the entire interest, as shown by assignments of record in this offiee; and that the said Letters Patent should be read with this correction therein that the same may conform to the record of the casein the Patent Offiee.

Signed, eounters igned, and sealed this 4th day of June, A. D. 1889.
